Primary 3 Science - Life Cycles Quiz 01 - Answer Key
Section A: Multiple Choice Questions (1 mark each)
1. B) Egg → Caterpillar → Pupa → Butterfly
This is the correct sequence of the butterfly's life cycle, also known as complete metamorphosis.
2. C) Pupa
During the pupa stage, the insect is enclosed in a cocoon/chrysalis and does not eat. It is transforming into an adult.
3. B) As an egg
A frog begins its life as an egg, usually laid in water.
4. B) Gills
Tadpoles live in water and breathe using gills, like fish.
5. C) Chicken
A chicken does not go through metamorphosis. The young chicken (chick) looks like a smaller version of the adult.
Section B: Short Answer Questions (2 marks each)
6. Egg, caterpillar (larva), pupa (chrysalis), butterfly (adult)
Award 0.5 marks for each stage correctly named
7. The tadpole grows legs (back legs first, then front legs). Its tail becomes shorter and eventually disappears. It develops lungs to breathe air. Its gills disappear.
Award 2 marks for mentioning at least 2 changes
8. Metamorphosis is the process where an animal goes through major changes in its body form as it grows from young to adult.
Accept: A big change in body form during an animal's life cycle
9. A chicken has 3 stages (egg → chick → adult chicken) and the young looks like the adult. A butterfly has 4 stages and goes through complete metamorphosis where the young (caterpillar) looks very different from the adult.
Award 2 marks for mentioning difference in stages or appearance
10. Butterflies lay their eggs on leaves of plants. This is so the caterpillar can have food to eat immediately after hatching.
Award 1 mark for where, 1 mark for why
Section C: Application Questions (2 marks each)
11. Egg → Tadpole → Froglet (with tail) → Adult frog
Award 2 marks for correct sequence
12. A caterpillar eats a lot of food to store energy for the pupa stage. During the pupa stage, it does not eat, so it needs stored energy to transform into a butterfly.
Award 2 marks for mentioning energy storage for pupa/transformation stage
13. The froglet uses lungs to breathe. Since it can hop on land, it needs lungs to breathe air. The gills would have disappeared or reduced by this stage.
Award 2 marks for correct answer (lungs) with explanation
14. Both go through metamorphosis, but a frog has 4 stages with the tadpole living in water, while a mealworm has 4 stages (egg, larva, pupa, beetle) all living on land.
Accept: Frog tadpole lives in water, mealworm larva lives on land / Different environments
15. The pupa will become a butterfly (or moth). He should wait about 1-2 weeks depending on the species.
Award 1 mark for butterfly/moth, 1 mark for time frame (accept 1-3 weeks)
